"dump -L -C32 .. | gzip -3c" stuck under -current

Hi,
when doing a `dump -L -C32 -f - / | gzip -3c > /mnt/bla/fasel` of an ~30GB 
filles FS I got:
...
Dump of root level 0 for >/<
   DUMP: Date of this level 0 dump: Sun Sep 26 17:13:14 2004
   DUMP: Date of last level 0 dump: the epoch

   DUMP: 85.89% done, finished in 0:09 at Sun Sep 26 18:17:21 2004

at that point gzip (or dump?) got stuck.
gzip where (accodingly to top) in the state 'piperd'

Are there any known issues with pipes or snapshots?

a `dump -L -C32 -f /mnt/bla/fasel /` afterwards completed successfully BTW.
